I too have lost my tool bar. I'm using a PC laptop and a Mac OSX and can't find my tool bar, history, bookmarks and files in the tool bar on either computer. Is it Yahoo that is screwing up or Firefox? Can't figure it out! Now using Safari. Had another problem with Yahoo Sports articles, when I clicked on a headline under sports I keep getting the message"fail" and could not read the entire article. All this happening in the past two weeks.
